The first two statements shows the same information. The third statement (In taste tests, 5713 more people preferred "Bolda Cola" to "Cola Nola") shows a difference of the amount of people that preferred "Bolda Cola" to "Cola Nola".

Explain your answer. - It is possible that all four advertising claims are based on the same survey because all four shows the same information but each in a different way or is shown in a reduced way. The ratios 3 to 2 and 17,139 to 11,426 is very similar from each other but that the first ratio is reduced from the second ratio, and that 17,139 is about 60% of 28,565. C.

Why? -I think that the second comparison (In taste tests, people who preferred "Bolda Cola" outnumbered those who preferred "Cola Nola" by a ratio of 17,139 to 11,426) is the most accurate way to report the survey data because the advertisement show the data with a ratio of accurate exact numbers which can attract people to buy their product, but not in a clear visual way. D. Which comparison do you think would be the most effective advertisement for "Bolda Cola"? Why? - I think that the fourth comparison (In taste tests, 60% prefer "Bolda Cola" to "Cola Nola") would be the most effective advertisement for "Bolda Cola" because the advertisement shows the data with a percentage, which is a clear way to show the data and that percentages are easy to see visually, are easy to read, and are easy to understand which can attract people to but their product both clearly and visually. Problem 1.1 Follow-Up: 1. Write two more statements comparing the popularity of the two colas. Explain each statement you write. - 1. In taste tests, 1/5 out of the total amount of people in the survey more preferred "Bolda Cola" to "Cola Nola". 2. In taste tests, about 40% out of the total amount of people in the survey preferred "Cola Nola" than "Bolda Cola". Methods we used- 1. Using comparisons. 2.Understanding the advantages and disadvantages for each comparison. 3.Knowing when to use each comparison.
Vocabulary- Ratio- The relationship in quantity, amount, or size between two or more things. Difference- The amount by which things differ in quantity or measure. Percentage- A part of a whole number expressed in hundredths.

The Big Idea-
Many important practical and mathematical applications involve comparing quantities of one kind or another; it is important to know which method to use and how we should use them.
